There’s no point as a swamp cooler does not have heat to reject. A heat pump in a traditional AC works by making one side hot (outside) and one side cool (inside). A swamp cooler decreases temps by evaporating water, which absorbs energy.
Also, swamp coolers are only effective in very dry environments. Unless you’re in the desert it’s going to make it feel warmer by raising humidity significantly. A large part of why AC makes it feel nicer is reducing humidity, which allows sweat to work better.
I wonder if using a swamp cooler at the same time as AC would increase the efficiency 🤔
No, AC reduces humidity while swamp coolers increase humidity. They would directly conflict and just waste electricity
In my use case I often don’t really need to change the humidity at all, I just want to cool down.
Usually when thats the case though there’s enough of a breeze that I can just open the windows and that’s definitely more efficient than running active cooling 😅

That’s a great question.
At first I thought it’d be a wash. The heat absorbed by vaporizing the water in the swamp cooler will be released onto the evaporator coils of the AC, so that’s a net zero energy transfer.
However, air is not good at conducting heat. This water evaporation/condensation cycle might transfer heat from the air to the evaporator coils of the AC better.
You are going to have additional water and electricity costs from running the swamp cooler though, so I really don’t know. I suppose you could run the condensation from the AC back to the swamp cooler to greatly reduce water usage.
Could mitigate the water costs by draining the AC condensation into the swamp cooler 😅 and maybe could use the airflow from the AC to drive the swamp cooler instead of it having its own fan
I guess youd need some water purifier involved though, which would probably get rid of any efficiency benefits
Swamp coolers increase humidity not decrease it. You put water into them and the vapor goes into the air. AC is the opposite, it condenses water from the air and that’s why the drip tube is there.
The window hose is for exhausting hot air outside.
Swamp coolers are designed to exhaust cool wet air indoors.
Just park your swamp cooler in front of an open window or patio door. Increase air flow throughout the house with fans. Open upstairs windows to create a cross breeze to move out hot air that naturally convects, and crack downstairs windows to help vent out the increased moisture. It sounds counterintuitive, but you are not supposed to seal your house up like with AC. You want outside air coming in to vent out the humidity
Swamp cooler cools air by evaporating water which uses up the heat energy in the room. Air conditioner on the other hand takes the heat energy from inside and moves it outside. They work by a different principle. A swamp cooler with an exhaust went wouldn’t work because you’d then just be pulling in hot replacment air from somewhere else.
I suppose you could get a hose and connect it to the cooler and window. With a fan (blowing in), you would get cooler, wetter outdoor air.
